Description

Technical Field

[0001] The invention relates to the technical field of parts polishing equipment, in particular to a polishing device for manufacturing and processing engineering machinery parts and a use method thereof. Background Art

[0002] With the development of society, people's living standards are improving day by day, and people's various needs are also increasing. At the same time, the requirements for product quality are also constantly improving. Steel is an indispensable material in production operations, but in the process of producing steel plates, the plates need to be polished to remove impurities and burrs on the plates. The traditional polishing device consists of a stroke mechanism, a power mechanism and a polishing mechanism. During the polishing operation, the stroke mechanism drives the polishing mechanism to move according to the pre-set settings and polishes the workpiece. This is also the most widely used polishing device at present, with the advantages of simple structure, easy use and low cost.

[0003] When performing high-precision polishing on accessories, it is necessary to spray polishing solution on the outside of the accessories in advance, and then use a wool grinding wheel to fine-grind the outer wall of the accessories. When the high-speed rotating wool grinding wheel comes into contact with the polishing solution, the solution will diffuse all around, resulting in low application efficiency of the polishing solution and the wool wheel. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a polishing device for manufacturing and processing engineering machinery parts, comprising a mounting plate, a motor is fixedly connected to the top of the mounting plate, a driving gear is fixedly connected to the output shaft of the motor, a driving pipe is rotatably connected to the inner wall of the through hole of the mounting plate, a gear ring is fixedly connected to the outer wall of the driving pipe, and a feeding pipe is rotatably connected to the inner wall of the driving pipe;

[0005] The grinding mechanism includes a flow pipe connected to the bottom of the driving pipe, an end of the flow pipe away from the driving pipe is connected to a mounting box, the bottom of the mounting box is fixedly connected to a chassis, and the top of the chassis is fixedly connected to a wool wheel;

[0006] The spraying mechanism comprises a mounting plate fixedly connected to the top of the chassis, a fixing frame is fixedly connected to the top of the mounting plate, a plurality of sliding square tubes are connected through the side wall of the fixing frame, a piston block is slidably connected to the inner wall of the sliding square tube, a sliding groove is provided on the top of the mounting plate, a transmission tube is fixedly connected to the inner wall of the mounting plate, an atomizer is connected through the end of the transmission tube away from the sliding groove, an L-shaped slide plate is slidably connected to the inner wall of the sliding groove, a spring telescopic rod is fixedly connected to the side wall of the L-shaped slide plate, a control component is rotatably connected to the top of the mounting plate, a constraint component is fixedly connected to the side wall of the mounting box, a grinding mechanism and a spraying mechanism are arranged inside the equipment by utilizing the characteristic that the equipment generates a large centrifugal force during polishing, and before use, the mounting plate is mounted on the mechanical arm, and it is ensured that the external polishing solution can enter the circulation tube through the feed pipe. When the arm places the wool wheel on the surface of the accessory, the power of the motor is turned on, and the motor drives the driving tube and the circulation tube to rotate through the driving gear. The rotating circulation tube drives the chassis and the wool wheel to rotate through the installation box, and the rotating wool wheel polishes the outer wall of the accessory; the centrifugal force generated by the high-speed rotating installation box will force the piston block to slide outward along the inner wall of the sliding square tube, and the sliding piston block drives the L-shaped slide plate to move outward along the inner wall of the sliding groove synchronously through the spring telescopic rod, so that the L-shaped slide plate no longer covers the entrance of the transmission tube. At this time, the polishing solution on the top of the installation plate can reach the atomizer directly through the transmission tube, and the polishing solution sprayed outward from the atomizer will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel, thereby improving the polishing quality of the equipment.

[0007] Preferably, the control component includes a gear column rotatably connected to the top of the mounting plate, a gear rod is fixedly connected to the inner walls of several piston blocks, the inner wall of the mounting plate is rotatably connected to the outer wall of the output shaft of the motor, and utilizing the characteristic that the above-mentioned piston block moves outward under centrifugal force, a control component is arranged inside the device, when the piston block moves outward, the piston block will drive the corresponding gear rod to move synchronously, and in the process of the gear rod moving laterally, the gear rod will drive the gear column to rotate, and the rotation speed of the gear column will limit the speed at which multiple gear rods move laterally outward, through the application of the above-mentioned gear column and gear rod, the gear column can simultaneously control the speed at which multiple piston blocks and gear rods slide outward along the inner wall of the sliding square tube, so as to avoid uneven outward movement speeds of the piston blocks, causing the center of rotation of the wool wheel to shift, thereby affecting the polishing efficiency of the equipment.

[0008] Preferably, the constraint component includes a hydraulic telescopic rod fixedly connected to the side wall of the piston block, a spring fixedly connected to the side wall of the hydraulic telescopic rod, and a transmission round tube connected to the end of the hydraulic telescopic rod away from the piston block. Utilizing the characteristic that the piston block moves along the outer wall of the sliding square tube, the liquid on the top of the mounting plate will enter the groove formed by the piston block and the sliding square tube. As more liquid enters the circulation tube and the groove, the inertia generated by the rotation of the mounting box will also increase synchronously, thereby increasing the pressure applied by the wool wheel during grinding. Through the application of the above-mentioned components, the wool wheel can have a larger inertia when facing irregular accessories to avoid excessive obstruction of the wool wheel, which will cause the rotation speed of the mounting box to decrease.

[0009] Preferably, the constraint assembly also includes a fixed plate fixedly connected to the side wall of the installation box, the bottom of the fixed plate is fixedly connected to a hydraulic telescopic rod 2, and the end of the hydraulic telescopic rod 2 away from the fixed plate is fixedly connected to the installation block. The characteristic of controlling the outward movement of multiple gear rods by a single gear column ensures the outward movement speed of multiple piston blocks while ensuring the synchronous outward movement of the piston blocks, thereby ensuring that the depths of multiple grooves formed by the piston blocks and the installation plates inside the equipment are equal, and the volumes of polishing solutions accumulated in the multiple grooves are equal, thereby ensuring that the center of rotation of the installation box remains unchanged.

[0010] Preferably, the constraint assembly also includes a constraint ring fixedly connected to the side walls of several mounting blocks, the inner wall of the constraint ring is slidably connected to the outer wall of the mounting box, the outer wall of the transmission tube is fixedly connected to the inner wall of the mounting box, and the outer wall of the gear ring is meshingly connected to the outer wall of the driving gear. The above-mentioned polishing solution and centrifugal force are used to drive the piston block to move outward, and a constraint assembly is arranged inside the equipment. When the piston block moves outward, the piston block will squeeze the corresponding hydraulic telescopic rod 1, so that the solution inside the hydraulic telescopic rod 1 enters the hydraulic telescopic rod 2 through the transmission tube, and forces the hydraulic telescopic rod 2 to extend. The extended hydraulic telescopic rod 2 drives the constraint ring to slide downward along the outer wall of the mounting box through the mounting block, and the sliding constraint ring will limit the hair roots of the bottom wool wheel floating outward. Through the application of the above-mentioned components, the soft wool wheel is prevented from being affected by centrifugal force, and multiple hair roots spread around, reducing the contact area between the wool wheel and the accessories, making it difficult to effectively polish the bottom parts.

[0011] Preferably, one end of the transmission tube away from the hydraulic telescopic rod one is connected to the side wall of the hydraulic telescopic rod two, one end of the hydraulic telescopic rod one away from the piston block is fixedly connected to the inner wall of the mounting box, and the bottom of the sliding groove is connected to the inner wall of the transmission tube.

[0012] Preferably, the side wall of the gear rod is meshed with the outer wall of the gear column, the end of the spring telescopic rod away from the L-shaped slide is fixedly connected to the side wall of the piston block, and the end of the fixing frame away from the mounting plate is fixedly connected to the top of the inner wall of the mounting box. After the equipment completes polishing, the hydraulic telescopic rod is released, and then each component is reset. The constraint ring no longer restricts the wool wheel, so that the hair roots of the wool wheel can disperse themselves under the influence of residual centrifugal force, thereby avoiding the hardening of multiple hair roots due to the stickiness of the polishing solution, which affects the effect of subsequent polishing.

[0013] A method for using a polishing device for manufacturing and processing engineering machinery parts comprises the following steps:

[0014] S1: Start the device, install the motor on the robot arm, and ensure that the external polishing solution can enter the flow pipe through the feed pipe;

[0015] S2: Turn on the power, the motor drives the driving tube and the circulation tube to rotate through the driving gear and the gear ring, and the rotating circulation tube drives the installation box and the wool wheel to start the polishing process.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention utilizes the characteristic that the equipment generates a large centrifugal force during polishing. A grinding mechanism and a spraying mechanism are arranged inside the equipment. Before use, the mounting plate is mounted on the robot arm, and it is ensured that the external polishing solution can enter the circulation tube through the feed pipe. When the robot arm places the wool wheel on the surface of the accessory, the power of the motor is turned on. The motor drives the driving tube and the circulation tube to rotate through the driving gear. The rotating circulation tube drives the chassis and the wool wheel to rotate through the mounting box. The rotating wool wheel performs a polishing process on the outer wall of the accessory. The centrifugal force generated by the high-speed rotating mounting box will force the piston block to slide outward along the inner wall of the sliding square tube. The sliding piston block drives the L-shaped slide plate to move outward synchronously along the inner wall of the sliding groove through the spring telescopic rod, so that the L-shaped slide plate no longer covers the entrance of the transmission tube. At this time, the polishing solution on the top of the mounting plate can directly reach the atomizer through the transmission tube. The polishing solution sprayed outward from the atomizer will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel, thereby improving the polishing quality of the equipment.

[0018] (2) The present invention utilizes the characteristic that the piston block moves outward under the centrifugal force, and a control component is arranged inside the device. When the piston block moves outward, the piston block will drive the corresponding gear rod to move synchronously, and during the transverse movement of the gear rod, the gear rod will drive the gear column to rotate, and the rotation speed of the gear column will limit the speed at which multiple gear rods move outward. Through the application of the gear column and gear rod, the gear column can simultaneously control the speed at which multiple piston blocks and gear rods slide outward along the inner wall of the sliding square tube, thereby avoiding uneven outward movement speeds of the piston blocks, causing the center of rotation of the wool wheel to shift, thereby affecting the polishing efficiency of the equipment.

[0019] (3) The present invention utilizes the characteristic that the piston block moves along the outer wall of the sliding square tube. At this time, the liquid on the top of the mounting plate will enter the groove formed by the piston block and the sliding square tube. As more liquid enters the circulation tube and the groove, the inertia generated by the rotation of the mounting box will also increase synchronously, thereby increasing the pressure applied by the wool wheel during polishing. Through the application of the above-mentioned components, the wool wheel can have a larger inertia when facing irregular accessories to avoid excessive obstruction of the wool wheel, which would cause the rotation speed of the mounting box to decrease. In addition, by controlling the outward movement of multiple gear rods with a single gear column, the piston blocks that move outward synchronously can ensure the outward movement speed of multiple piston blocks while ensuring the outward movement speed of multiple piston blocks. This ensures that the depths of multiple grooves formed by the piston block and the mounting plate inside the equipment are equal, and the volumes of polishing solutions accumulated in the multiple grooves are equal, thereby ensuring that the center of rotation of the mounting box remains unchanged.

[0020] (4) The present invention utilizes the characteristics of the polishing solution and centrifugal force driving the piston block to move outward, and a constraint component is arranged inside the device. When the piston block moves outward, the piston block will squeeze the corresponding hydraulic telescopic rod 1, so that the solution inside the hydraulic telescopic rod 1 enters the hydraulic telescopic rod 2 through the transmission tube, and forces the hydraulic telescopic rod 2 to extend. The extended hydraulic telescopic rod 2 drives the constraint ring to slide downward along the outer wall of the mounting box through the mounting block, and the sliding constraint ring will limit the hair roots of the bottom wool wheel floating outward. Through the application of the above-mentioned components, the soft wool wheel is prevented from being affected by the centrifugal force, and multiple hair roots are spread around, reducing the contact area between the wool wheel and the accessories, making it difficult to effectively polish the bottom parts; after the equipment completes polishing, the hydraulic telescopic rod 1 is released, and then each component is reset. The constraint ring no longer restricts the wool wheel, so that the hair roots of the wool wheel can disperse themselves under the influence of residual centrifugal force, avoiding multiple hair roots from sticking and hardening due to the stickiness of the polishing solution, affecting the subsequent polishing effect.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1 - Figure 5 The present invention is a polishing device for manufacturing and processing engineering machinery parts, comprising a mounting plate 1, a motor 11 is fixedly connected to the top of the mounting plate 1, a driving gear 12 is fixedly connected to the output shaft of the motor 11, a driving tube 13 is rotatably connected to the inner wall of the through hole of the mounting plate 1, a gear ring 14 is fixedly connected to the outer wall of the driving tube 13, and a feeding tube 15 is rotatably connected to the inner wall of the driving tube 13;

[0035] The grinding mechanism 2 includes a flow pipe 21 connected to the bottom of the driving pipe 13, an end of the flow pipe 21 away from the driving pipe 13 is connected to a mounting box 22, a bottom of the mounting box 22 is fixedly connected to a chassis 23, and a top of the chassis 23 is fixedly connected to a wool wheel 24;

[0036] The spraying mechanism 3 includes a mounting plate 31 fixedly connected to the top of the chassis 23, a fixing frame 32 fixedly connected to the top of the mounting plate 31, a plurality of sliding square tubes 33 are connected through the side wall of the fixing frame 32, a piston block 34 is slidably connected to the inner wall of the sliding square tube 33, a sliding groove 35 is provided on the top of the mounting plate 31, a transmission pipe 36 is fixedly connected to the inner wall of the mounting plate 31, an end of the transmission pipe 36 away from the sliding groove 35 is connected through the atomizer 37, and the sliding groove 35 is provided at the bottom of the mounting plate 31. An L-shaped slide plate 38 is slidably connected to the inner wall, a spring telescopic rod 39 is fixedly connected to the side wall of the L-shaped slide plate 38, a control component 4 is rotatably connected to the top of the mounting plate 31, and a restraining component 5 is fixedly connected to the side wall of the mounting box 22. During polishing, the equipment generates a large centrifugal force. A grinding mechanism 2 and a spraying mechanism 3 are arranged inside the equipment. Before use, the mounting plate 1 is mounted on the robot arm, and it is ensured that the external polishing solution can enter the circulation tube 21 through the feed pipe 15. When the mechanical arm places the wool wheel 24 on the surface of the accessory, the power supply of the motor 11 is turned on. The motor 11 drives the driving tube 13 and the circulation tube 21 to rotate through the driving gear 12. The rotating circulation tube 21 drives the chassis 23 and the wool wheel 24 to rotate through the installation box 22. The rotating wool wheel 24 performs a polishing process on the outer wall of the accessory; the centrifugal force generated by the high-speed rotating installation box 22 will force the piston block 34 to slide outward along the inner wall of the sliding square tube 33. The sliding piston block 34 drives the L-shaped slide plate 38 to move outward along the inner wall of the sliding groove 35 synchronously through the spring telescopic rod 1 39, so that the L-shaped slide plate 38 no longer covers the entrance of the transmission tube 36. At this time, the polishing solution on the top of the installation plate 31 can directly reach the atomizer 37 through the transmission tube 36. The polishing solution sprayed outward by the atomizer 37 will diffuse to the surroundings under the action of centrifugal force. Through the application of the above components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel 24, thereby improving the polishing quality of the equipment.

[0037] For example 2, please refer to Figure 6 - Fig. 9The present invention is a polishing device for manufacturing and processing engineering machinery parts. On the basis of the first embodiment, the control component 4 includes a gear column 41 rotatably connected to the top of the mounting plate 31, and a gear rod 42 is fixedly connected to the inner wall of a plurality of piston blocks 34. The inner wall of the mounting plate 1 is rotatably connected to the outer wall of the output shaft of the motor 11. By utilizing the characteristic that the piston block 34 moves outward under the centrifugal force, a control component 4 is arranged inside the device. When the piston block 34 moves outward, the piston block 34 will drive the corresponding gear rod 42 to move synchronously. During the transverse movement of the gear rod 42, the gear rod 42 will drive the gear column 41 to rotate, and the rotation speed of the gear column 41 will limit the speed at which the plurality of gear rods 42 move outward. Through the application of the gear column 41 and the gear rod 42, the gear column 41 can simultaneously control the speed at which the plurality of piston blocks 34 and the gear rod 42 slide outward along the inner wall of the sliding square tube 33, so as to avoid the piston block 34 moving outward at different speeds, causing the rotation center of the wool wheel 24 to shift, thereby affecting the polishing efficiency of the device.

[0038] The constraint component 5 includes a hydraulic telescopic rod 51 fixedly connected to the side wall of the piston block 34, and a spring 52 is fixedly connected to the side wall of the hydraulic telescopic rod 51. The end of the hydraulic telescopic rod 51 away from the piston block 34 is connected with a transmission round tube 53. By utilizing the characteristic that the piston block 34 moves along the outer wall of the sliding square tube 33, the liquid on the top of the mounting plate 31 will enter the groove formed by the piston block 34 and the sliding square tube 33. As more liquid enters the circulation pipe 21 and the groove, the inertia generated by the rotation of the mounting box 22 will also increase synchronously, thereby increasing the pressure applied by the wool wheel 24 during grinding. Through the application of the above-mentioned components, the wool wheel 24 has a larger inertia when facing irregular accessories to avoid excessive obstruction of the wool wheel 24, which causes the rotation speed of the mounting box 22 to decrease.

[0039] The constraint assembly 5 also includes a fixed plate 54 fixedly connected to the side wall of the installation box 22, and a hydraulic telescopic rod 55 is fixedly connected to the bottom of the fixed plate 54, and a mounting block 56 is fixedly connected to the end of the hydraulic telescopic rod 55 away from the fixed plate 54. The characteristic of controlling the outward movement of multiple gear rods 42 through a single gear column 41 ensures the outward movement speed of multiple piston blocks 34 while ensuring that the piston blocks 34 move outward synchronously, ensuring that the depths of multiple grooves formed by the piston blocks 34 and the mounting plates 31 inside the equipment are equal, and the volumes of polishing solutions accumulated in the multiple grooves are equal, thereby ensuring that the center of rotation of the installation box 22 remains unchanged.

[0040] The constraint assembly 5 also includes a constraint ring 57 fixedly connected to the side walls of the plurality of mounting blocks 56. The inner wall of the constraint ring 57 is slidably connected to the outer wall of the mounting box 22. The outer wall of the transmission tube 53 is fixedly connected to the inner wall of the mounting box 22. The outer wall of the gear ring 14 is meshedly connected to the outer wall of the driving gear 12. The above-mentioned polishing solution and centrifugal force drive the piston block 34 to move outward. The constraint assembly 5 is arranged inside the device. When the piston block 34 moves outward, the piston block 34 will squeeze the corresponding hydraulic telescopic rod 51, so that the hydraulic telescopic rod 51 is The solution in 1 enters into 4 the hydraulic telescopic rod 2 55 through the transmission tube 53, and forces the hydraulic telescopic rod 2 55 to extend. The extended hydraulic telescopic rod 2 55 drives the constraint ring 57 to slide downward along the outer wall of the installation box 22 through the installation block 56, and the sliding constraint ring 57 will limit the hair roots of the bottom wool wheel 24 that float outward. Through the application of the above components, the soft wool wheel 24 is prevented from being affected by centrifugal force, and multiple hair roots are spread around, which reduces the contact area between the wool wheel 24 and the accessories, making it difficult to effectively polish the bottom parts.

[0041] One end of the transmission tube 53 away from the hydraulic telescopic rod 1 51 is connected to the side wall of the hydraulic telescopic rod 2 55, and one end of the hydraulic telescopic rod 1 51 away from the piston block 34 is fixedly connected to the inner wall of the mounting box 22, and the bottom of the sliding groove 35 is connected to the inner wall of the transmission tube 36.

[0042] The side wall of the gear rod 42 is meshed with the outer wall of the gear column 41, the end of the spring telescopic rod 39 away from the L-shaped slide plate 38 is fixedly connected to the side wall of the piston block 34, and the end of the fixed frame 32 away from the mounting plate 31 is fixedly connected to the top of the inner wall of the mounting box 22. After the equipment completes polishing, the hydraulic telescopic rod 51 is released. Next, each component is reset, and the constraint ring 57 no longer restricts the wool wheel 24, so that the hair roots of the wool wheel 24 can disperse themselves under the influence of residual centrifugal force, thereby avoiding the hardening of multiple hair roots due to the stickiness of the polishing solution, which affects the effect of subsequent polishing.

[0043] The method for using the polishing device for manufacturing and processing engineering machinery parts comprises the following steps:

[0044] S1: Start the device, install the motor 11 on the robot arm, and ensure that the external polishing solution can enter the flow tube 21 through the feed pipe 15;

[0045] S2: Turn on the power supply, the motor 11 drives the driving tube 13 and the circulation tube 21 to rotate through the driving gear 12 and the gear ring 14, and the rotating circulation tube 21 drives the installation box 22 and the wool wheel 24 to start the polishing process.

[0046] A specific application of this embodiment is: before use, the mounting plate 1 is mounted on the robot arm, and it is ensured that the external polishing solution can enter the circulation tube 21 through the feed pipe 15. When the robot arm places the wool wheel 24 on the surface of the accessory, the power of the motor 11 is turned on, and the motor 11 drives the driving tube 13 and the circulation tube 21 to rotate through the driving gear 12. The rotating circulation tube 21 drives the chassis 23 and the wool wheel 24 to rotate through the mounting box 22. The rotating wool wheel 24 performs a polishing process on the outer wall of the accessory; the centrifugal force generated by the high-speed rotating mounting box 22 will force the piston The block 34 slides outward along the inner wall of the sliding square tube 33, and the sliding piston block 34 drives the L-shaped slide plate 38 to move outward synchronously along the inner wall of the sliding groove 35 through the spring telescopic rod 39, so that the L-shaped slide plate 38 no longer covers the entrance of the transmission tube 36. At this time, the polishing solution on the top of the mounting plate 31 can reach the atomizer 37 directly through the transmission tube 36. The polishing solution sprayed outward by the atomizer 37 will diffuse to the surroundings under the action of centrifugal force. Through the application of the above-mentioned components, the polishing solution diffused from the center of the equipment to the surroundings will increase the contact area between the solution and the wool wheel 24, thereby improving the polishing quality of the equipment.

[0047] Taking advantage of the characteristic that the piston block 34 moves outward under the centrifugal force, a control component 4 is provided inside the device. When the piston block 34 moves outward, the piston block 34 will drive the corresponding gear rod 42 to move synchronously. During the transverse movement of the gear rod 42, the gear rod 42 will drive the gear column 41 to rotate, and the rotation speed of the gear column 41 will limit the speed at which the multiple gear rods 42 move outward. Through the application of the gear column 41 and the gear rod 42, the gear column 41 can simultaneously control the speed at which the multiple piston blocks 34 and the gear rod 42 slide outward along the inner wall of the sliding square tube 33, thereby avoiding uneven outward movement speeds of the piston block 34, causing the center of rotation of the wool wheel 24 to shift, thereby affecting the polishing efficiency of the equipment.

[0048] By utilizing the characteristic that the piston block 34 moves along the outer wall of the sliding square tube 33, the liquid on the top of the mounting plate 31 will enter the groove formed by the piston block 34 and the sliding square tube 33. As more liquid enters the circulation tube 21 and the groove, the inertia generated by the rotation of the mounting box 22 will also increase synchronously, thereby increasing the pressure applied by the wool wheel 24 during polishing. By applying the above-mentioned components, the wool wheel 24 can have a larger inertia when facing irregular accessories, thereby preventing the wool wheel 24 from being obstructed too much, thereby causing the rotation speed of the mounting box 22 to decrease. In addition, by controlling the outward movement of multiple gear rods 42 through a single gear column 41, while ensuring the outward movement speed of multiple piston blocks 34, the piston blocks 34 that move outward synchronously ensure that the depths of multiple grooves formed by the piston blocks 34 and the mounting plate 31 inside the equipment are equal, and the volumes of polishing solutions accumulated in the multiple grooves are equal, thereby ensuring that the center of rotation of the mounting box 22 remains unchanged.

[0049] Taking advantage of the polishing solution and the centrifugal force driving the piston block 34 to move outward, a constraint assembly 5 is provided inside the device. When the piston block 34 moves outward, the piston block 34 will squeeze the corresponding hydraulic telescopic rod 1 51, so that the solution inside the hydraulic telescopic rod 1 51 enters the inside of the hydraulic telescopic rod 2 55 through the transmission tube 53, and forces the hydraulic telescopic rod 2 55 to extend. The extended hydraulic telescopic rod 2 55 drives the constraint ring 57 to slide downward along the outer wall of the installation box 22 through the installation block 56, and the sliding constraint ring 57 will limit the bottom wool wheel The hair roots of the wool wheel 24 that float outward can be prevented from being affected by the centrifugal force on the soft wool wheel 24 by the application of the above-mentioned components. The multiple hair roots spread outward, reducing the contact area between the wool wheel 24 and the accessories, making it difficult to effectively polish the parts at the bottom. After the equipment completes polishing, the hydraulic telescopic rod 51 is released, and then each component is reset. The restraint ring 57 no longer restricts the wool wheel 24, so that the hair roots of the wool wheel 24 can disperse themselves under the influence of the residual centrifugal force, thereby preventing the multiple hair roots from sticking and hardening due to the stickiness of the polishing solution, which affects the effect of subsequent polishing.
